ussd: Ignore connection release/clear from the MSC

In case this is a local USSD connection we will ignore
the clear command and respond with a RLC to any RLSD but
will never forward that to the BSC. This way the external
USSD is fully in charge of the connection.
There are theoretical issues if there are multiple transactions
on the same SCCP Connection but this can not be solved properly
right now.
